Hello and welcome to the forum. Very sorry to hear about your mother in law. Is there any update? Is she still having the screaming and moaning? That must be very hard to deal with. Is she in care at a rehabilitative unit? What are they doing to help her recover from the stroke? Something to ask her caregivers about is pseudobulbar affect. https://www.stroke.org/en/about-stroke/effects-of-stroke/emotional-effects-of-stroke/pseudobulbar-affect This can show itself as these types of emotional outbursts. However, this is usually brief periods and you describe it going on much longer. It's been a couple of weeks since you posted this, is there any update?
